CNVs were detected by comparison to the common Illumina-reference set of 87 CEU samples specific for the Q610 array and visualized in Nexus (version 4.1) software as log2 ratios (http://www.biodiscovery.com/index/nexus).com/index/nexus
The QTL analysis could then be performed on these functions, thus accounting for the systematic within-tree variability and increasing the relevance of detected QTL in comparison with analyses performed on samples specific for a certain tree age or annual ring.
We determined that the limit of detection (LOD) was compound and sample specific, although for most compounds the LOD was < 10 pg/g.
A further PCR step was performed to include sample specific barcodes for parallel sequencing using the 454/Roche pyrosequencing platform [35].
The mean of the features in each set was taken to be the sample specific score for that pathway.
Possible negative effects as well as gender-specific results should be further monitored, although the gender effects observed in our study may well be sample-specific, for our male subsample was quite small (n = 24).
The average sample specific detection limit for arsenic was 0.003 μg/g.
Sample specific OTU counts for nocardicin, rifamycin, bleomycin, and daptomycin clusters are shown.
Control samples with cells alone (no enzyme) were included, and 'cells alone' specific activities were subtracted from experimental sample specific activities control for the effect of autolysis.
For mouse samples, specific conditions for each pathway signature can be found in Additional file 4. For human breast tumor samples, pathway activation was predicted using Score Signatures [ 34] and conditions can be found [ 2].
When DNA is limiting, as in viral community samples or microbial communities of permafrost soils or air samples, specific recommendations for quantitative metagenomics are as follows.
